You may recall that in October 2019 the government released a consultation on the proposed changes to Part L (conservation of fuel and power) and F (ventilation) of the Building Regulations – called 'The Future Homes Standard’ (as we reported here). The second part of the consultation has now been published (here) as 'The Future Buildings Standard’.
This consultation closes on 13 April 2021 and looks at changes to Part L and Part F of the Building Regulations for non-domestic buildings and dwellings; and overheating in new residential buildings.
Prior to this consultation, and accordance with the Climate Change Committee’s statutory report in 2015, the government conducted research (report here) into overheating in new homes. It highlighted that during warm years most new homes in England would experience overheating, with London having a particular issue because of its higher temperatures. Overheating can impact on the health and welfare of the occupants and these issues can be associated with sleep loss. One of the questions posed in this consultation is whether the reduction of window sizes to mitigate overheating would provide adequate daylight and avoid the need for excess lighting in winter. As part of the consultation, internal curtains and blinds and overshading from trees are to be excluded as means of shading.
